Abstract: RCA 85,724 Abstract of the Disclosure A detector for detecting motion in an image represented by a video signal includes delay means for concurrently providing lines of signal from five consecutive fields. Sums of signals from first and second fields are subtracted from sums of signals from third and fourth fields to generate first motion indicators. Differences of signals from the first and second fields are subtracted from differences of signals from the third and fourth fields to generate second motion indicators. Differences of signals from the first and fifth fields are generated to form third motion indicators. The first, second and third motion indicators are compared and the largest is provided as a motion signal which is subsequently limited, spread and scaled.

Title: Crossover mold tool for consolidating composite materials
Inventor: PRATT RICHARD D
IPC: B29C53/02
Filed: 1991-03-14
Abstract: ABSTRACT OF THE DISCLOSURE        A curved composite material body is consolidated to a complexly curved shape by placing rigid tooling on the concave-facing side of the body, and a pressure membrane on the other (convex-facing) side of the body.  In another region of the body where the sign of the curvature of the body changes so that the other side becomes the concave-facing side, the rigid tooling is placed on that side, against the concave-facing side, and the pressure membrane is contacted to the convex-facing side.  The rigid tooling thus crosses over from one side to the other through various regions of the body, providing a precise consolidation to meet the structural and dimensional specifications.  Consolidation is achieved by applying pressure to the body of composite material through the pressure membranes.

Inventor: PUSCH REINHARD
IPC: H01R12/79
Filed: 1991-09-05
Abstract: For  the  purposes  of  connecting  and  joining conductive traces on printed circuit boards, the stripped ends of a flexible multi-conductor flat cable are inserted into metallized openings in the printed circuit boards. The cables are cut to length and their ends are stripped of insulation and supported in an injection molded bar member. Those ends are desirably not to be bent in storage and transportation.  In order to protect them, a U-shaped device is pushed onto the bar member over the cable ends.   The bottom plate portion of the device has holes of a conical configuration.   In a transportation position the ends are disposed within the walls of  those holes  and are held therein.  The device latches in the transportation position. For the ends to be inserted into the holes in the printed circuit board the device is pushed further onto the cable ends in an operative position.  As such, the ends pass in a guided fashion through the holes in the bottom plate portion and into the holes in the printed circuit board.

Title: A network independent clocking circuit which allows a synchronous master to be connected to a circuit switched data adapter
Inventor: RENNER ROBERT E
IPC: H04J3/06
Filed: 1991-09-19
Abstract: In order to accomplish the object of the present invention there is provided a network independent clocking (NIC) circuit which allows a local synchronous master to exchange data with a local data adapter. The NIC circuit includes a phase measuring block for continually generating a local phase difference indicator, where the local phase difference indicator indicates a phase relation between the local data adapter and the local synchronous master. The local phase difference indicator is transmitted to a remote data adapter. Back locally, a phase difference indicator is received from a remote data adapter. A baud clock is generated and used to transfer data from the data adapter to the synchronous master, the baud clock generator uses the phase difference indicator to recreate the phase difference between the remote data adapter and the remote synchronous master.

Patent CA-2056578-A1 (CA)
Inventor: KIRSCHNER MARK J
IPC: F25D9/00
Filed: 1991-11-28
Abstract: The present  invention provides a food processing system and  method  for  refrigerating  articles  of  food.   The  food processing system includes at least two cooling stages formed by a cryogenic freezer and a hydrocooler.   The cryogenic freezer receives  the  articles  of  food  and  transfers  heat  from the articles of food to the cryogen so that the articles of food are refrigerated.  After the transfer of heat from the articles of food to the cryogen,  the cryogen boils off to form cryogenic vapor.  The hydrocooler  receives the articles of food prior to the cryogenic freezer and transfers heat from the articles of food to supplied cooling water.  Such heat transfer reduces the quantity of  cryogen  required to  refrigerate  the  articles  of food.  Additionally, an eductor is connected to a pump and to vent  line from the cryogenic  freezer.   The cooling water  is pumped through the eductor to suction cryogenic vapor from the cryogenic freezer and to mix the cryogenic vapor and the cooling water prior  to  reception  of  the  cooling  water  in  the hydrocooler.  Such mixing transfers heat from the cooling water to the cryogenic vapor to increase the heat transfer between the articles and the cooling water in the hydrocooler.  As a result of such increased heat transfer, the amount of cryogen required in refrigerating the articles is further reduced.   The eductor and pump combination has general application to the cooling of articles.

Title: Laminated adhesive core chain saw guide bar with containment and spacing wire
Inventor: O'NEEL TIMOTHY H
IPC: B27B17/00
Filed: 1992-01-06
Abstract: ABSTRACT OF THE DISCLOSURE    A chain  saw guide  bar  assembly  includes  opposing  outer laminates in spaced relation as defined by a wire structure lying generally about the periphery of the laminates, but spaced inwardly of the edge boundary thereof whereby a saw chain groove formation results as defined by an exposed or outward facing portion of the wire structure and exposed portions of the inner surfaces of the outer laminates.  The wire structure advantageously provides, in combination with the outer laminates, a containment cavity for a foam-adhesive core laminate which expands upon curing to fill the cavity and to adhere to the inner surfaces of the outer laminates.          A very rigid yet lightweight chain saw bar results with less production complexity and cost relative to that of other core laminate chain saw bars.
